Answer:
It refers to selective observation.
Step-by-step explanation:
Investigations are the methods used by scientists to obtain information on a specific topic; in some investigations, they can have different effects such as biases in the study or an unexpected situation. For example, selective observation can be presented.
Selective observation refers to the decisions made by the researcher when choosing specific situations to observe, losing sight of the other elements involved in the study, so these actions produce a bias in the investigation because they do not have all the required information.
For example, in the case of Katie, after the investigation progresses, she focuses on situations that resemble her conclusion, so she loses sight of the other situations that could be observed, so she is making a selective observation.
